Apple's annual developer conference, the WWDC 2015 kicks off at the Mascone Center in San Francisco at 10 AM Pacific Time today. You can view the entire stream live at Apple's website or join us for a live blog. Here are a few things you can expect from the event:

iOS 9

Apple usually updates its mobile operating system each year, so expect to see iOS 9 at today's keynote. The new OS is set to include an enhanced Siri along with major performance improvements for legacy devices.

A brand new OS X

OS X Yosemite was a huge step ahead for Apple. The amazing visual overhaul, features like continuity and hand off made for a compelling upgrade. Though little is known about the new version, pictures of banners posted by MacRumors show OS X, iOS and watchOS in symmetric geometrical figures. Guess we'll have to wait for a few more hours to find out what Apple beings to the table.

A new Music Streaming Service

Ever since Apple's acquisition of Beats Electronics last year, rumors of a new music streaming service have been floating the blogosphere. We can expect the new streaming service to be branded as Apple Music and if reports are true, the first the months will be free as a trial. For subsequent months, Apple is expected to charge $10 each month.

watchOS

The Apple Watch currently runs on top of a heavily robbed down version of iOS. As spotted at Mascone West, Apple is about to brand the new OS inconspicuously as watchOS. The watch is expected to get new native apps along with a performance boost.

Smart Home Products

Apple announced HomeKit — its smart home software — a year ago, and the first products supporting it just went on sale. That could be all the smart home news that Apple has for the moment, but it's possible that it'll discuss further plans on Monday. A dedicated "Home" app could be added to iOS, according to 9to5Mac, which would make Apple's ambitions in this space even more prominent.

Finally, improvements for Swift

Last year, Apple did something that probably not even the best leakers had dreamt of - Swift. The new language is now a hot favorite amongst the developer community and has reached the 22nd spot in the sea of languages that have been here since time immemorial. Apple is expected to deliver performance improvements for Swift, making it easier to compile heavy apps even on older Macs.
Another not so important change will be the font. Apple is doing away with their current system fonts and will opt for the new San Francisco font that debuted with the Apple Watch. This will probably sum it up but we do expect Apple to surprise us. Join us tonight as we bring to you the event live on twitter.
